a) MAD for the forecast developed by the management's technique = sales (round your response to two decimal places). MAPE for the forecast developed by the management's technique =% (round your response to two decimal places). b) Using the Naive Method, the forecast for period March through June is (round your response to two decimal places): MAD for the naive forecast = sales (round your response to two decimal places) MAPE for the forecast developed by the naive approach = % (round your response to two decimal places). c) When comparing MAD for the two approaches, the better forecast is achieved using the When comparing MAPE for the two approaches, the better forecast is achieved using the
